ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 727,069, dated May 5, 1903. Application filed February 24, 1903. Serial No. 144,663. (No model.)

To all whom it may concern.-

Be it known that I, CARL BOMEISLER, a citizen of the United States, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in Atomizers, of which the following is afull, clear, and exact specification.

My invention relates to improvements in spraying apparatus, and more particularly to that class wherein the liquid is forced from its receptacle by means of a cylinder-pump; and the object of this invention is to provide a neat, simple, and inexpensive atomizer composed of few parts, which are easy to assemble and not liable to get out of order in the course of operation.

Up to the present time atomizers incorporating in their construction a pump, as above mentioned, have proven unsatisfactory owing to the imperfect working of the pistons and valves therein. A solid metal piston without packing has been found wholly unsuited for the purpose, since it does not prevent the escape of air between its edge and the inner wall of the pump-cylinder. The piston packed with a rubber washer or gasket is unreliable and soon wears out, and frequently the rubber is affected by contact with the fluid to be sprayed or the vapors arising therefrom, and thus rendered unfit for use, and finally pistons provided with leather packings in the customary manner have proven unsatisfactory, owing to the fact that in apparatus of this kind which are designed for occasional use only and then for short periods at a time the leather packings dry out and shrink up, and consequently render the pump inoperative until the same have been again soaked and worked into condition. To correct these defects and to attain the ends hereinabove set forth is the object of my inaccording to and embodying my invention. Fig. 2 is a section taken on the line 2 2 of Fig. 1. Fig. 3 is an inverted bottom View of the pump. Fig. 4 is a similar view of the cap for inclosing the upper end of the pump-cylinder; andFig. 5 is a detail section of the lower portion of the cylinder, showing the annular groove therein and the valve arranged at the bottom of the cylinder.

In said drawings, A designates a fluid-receptacle, which may be of glass or other material and of any desirable size and shape and provided at its top with a neck or reduced portion B, upon which is cemented or otherwise secured a sleeve 0, having a reduced top O,-provided upon its inner surface with screw-threads a.

D denotes a pump-cylinder provided near its'upper end with a projecting flange E, provided upon its under side with an annular recess b, in which is disposed a gasket or packing 0, adapted to contact with the edge of the reduced top 0', and upon the outer surface of said cylinder, below the flange E, are screwthreads d, adapted to engage the threads (1 of the sleeve 0, whereby to support the cylinder D duly within the receptacle A and at the same time perfectly seal the open upper end thereof.

Upon the inner surface of the cylinder D,

near its lower end, is provided an annular groove or recess F, and in the bottom of said cylinder is a port G, provided with a valve H, made of very thin non-corrosive metal, having an integral tongue H, which is secured at its end to the cylinder D, whereby to maintain said valve normally spring-pressed against the under side of bottom of the cylin- (161' D to seal the port G therein.

I denotes a delivery-tube secured to the outer surface of the cylinder D, having its lower end extending downwardly into the receptacle A and the fluid therein and its upper end extending into the flange E, where it is connected to the spraying-nozzle J.

Within the cylinderD is arranged a piston K, consisting of a disk or disks of leather L, cupped, as shown, and securedupon the end of a rod M intermediate the metal washer e and head f, the said rod M being further provided with a spline M, which extends almost to the upper end thereof, and N denotes a button or knob secured upon the upper pro jecting end of said rod M.

The piston K and rod M are maintained duly in position within the cylinder D by a cap 0, which may be screwed upon or otherwise secured to the open upper end of the cylinder, said cap being provided with a central aperture P, having a recess g opening into the same, and h h denote studs depending from the under side of said cap to each side of the recess g, which are adapted to contact with the sides of the spline M to limit the rotary movement of said rod and piston when the same are depressed within the cylinder when not in use.

Q denotes a coil-spring interposed between the bottom of the cylinder D and the under side of the piston disk or disks L, whereby to maintain the edge or side thereof expanded into the recess F in the cylinder when the pist-on is secured in its depressed position and to elevate the piston after each depression when the atomizer is inoperation.

The operation of the atomizer is as follows: Assuming the apparatus to be in the position shown at Fig. 1, with the piston secured in its depressed position within the cylinder, it simply becomes necessary to partially rotate the rod M by means of the knob N until the spline M thereof is brought into register with the recess g in the cap 0, whereupon said rod M and piston K will at once be projected upwardly by the action of the spring Q, and in so doing a partial vacuum will be caused in the lower part of the cylinder below the piston K, and in consequence thereof the air at atmospheric pressure in the upper portion of the cylinder above-the piston will be forced between the edge of the leather disk L and the inner wall of the cylinder into the lower part of said cylinder, and with the depression of piston the air in said lower portion of the cylinder will be compressed and forced through the port G and past the valve H into the receptacle A above the fluid therein and cause the fluid to rise in the delivery-tube I and issue from the sprayingnozzle J. By continuingtheoperation above described the air will be compressed within the receptacle and the fluid caused to issue from the nozzle J in the form of a continuous spray.

It is to be noted that in the operation above described the piston K, owing to the peculiar construction of the disk L, acts also as a valve, which permits the air drawn into the cylinder through the aperture P and recess g when the piston and rod are depressedto pass by its edge during its upward movement and be compressed with the next depression of the rod and piston and the escape of air in the course of this second depression prevented by the action of the disk L in having its edge pressed against the inner wall of the'cylinder and by the valve H in being'pressed against its seat upon the valve port G, the closure of the valve Q being rendered more perfect and efiective by reason of its becoming moistened by the fluid within the receptacle.

It will of course be understood that I do not wish to limit myself to the location of the recess F within the cylinder, as the same maybe arranged at any desired point therein, and by simply modifying or rearranging'the locking device the same maybe caused to hold the disk L expanded into the recess.

Without limiting myself to the details of construction, which may be varied within the scope of the invention, what I claim, and desire to seciire by Letters Patent, is

1. An atomizer comprising areceptacle, a delivery-tub, a cylinder adapted for securement within said receptacle, having air-ports therein, a recess in the inner surface of said cylinder, a piston arranged within said cylinder, and means for maintaining said piston in position therein and fill said recess, substantially as specified.

6. An atomizer comprising a receptacle, an opening therein, a cylinder provided with a delivery-tube and nozzle, and a flange adapted for securement intermediate its ends within said receptacle and seal the openingtherein, an annular recess in the inner surface of said cylinder adjacent to its base, a cap for closing the upper end of said cylinder having an aperture and recess therein, an outlet-port in the base of said cylinder, a valve therefor, a piston in said cylinder having a yielding packing turned over at its edge, a rod extending upwardly therefrom and through the aperture in the cap, a head at its upper end, a spline arranged upon the side of said rod extending almost to its upper end, stops arranged upon the under side of said cap adapted to contact with said spline to limit its rotary movement, and a spring disposed in said cylinder intermediate its bottom and the piston, substantially as specified.
